As the owner of a P71 Crown Vic, I can say it's not exactly a quick car (though I'm still bummed that Ford is axing the civilian version). Oh, sure, the 4.6 has decent torque and moves two tons of steel well enough to get the job done… but what happens when you say "Damn the transmission, full speed ahead!" and jolt your Crown Vic's engine with a healthy shot of En Two Oh? Good stuff, that's what happens. Watch the before-and-after runs of drivers Kellydood and Quickvic to see (and hear) what I mean. Yes, this does give me ideas…
